General Description:
The CN5815 is a current mode fixed-frequency PWM controller for high brightness(HB) LED driving applications. The device operates from an input supply between 4.5V and 32V and provides to drive an external N-channel MOSFET.
The CN5815 contains all the necessary building blocks including a bandgap reference, a 330KHz oscillator, current-mode control circuitry, chip shutdown block, softstart block and gate driver, etc. LED current is set by an external resistor.
